Let $G$ be a loopless graph with maxmaxflow $\Lambda$, and let $P_G(q)$ be its chromatic polynomial. Maxmaxflow chromatic positivity conjecture. For every real $q>\Lambda$, … In pa…

Let $B_{m,n}(x)$ be the box polynomial, and consider its complex roots. The notation $O(m\cdot\sqrt{n})$ denotes an asymptotic upper bound in the parameters $m$ and $n$. Imaginary-…
